OPERATION MANUAL
4. OPERATION
4.1 GETTING STARTED
• Loosen the Roller Tensioner Lever lock nut (Fig.10)
• Loosen the Roller Tensioner Lever (39#) by turning the
lever in a counter-clockwise direction. (Fig 9).
Note:
The through hole in the upper frame is slotted. The
Upper Roller Shaft and Bearing Block should be free to
be raised up sufficiently to separate the Bead Roller Dies
enough to slide the workpiece metal between them . If
the upper Bearing Block is hard to move see “Adjusting
The Top Bearing Block” (Page. 13)
• Center the Upper Die over the previously drawn
pattern line then move the Upper Roller Shaft and
Bearing Block down in place against the metal work
piece.
• Check the alignment with the drawn line, then increase
the pressure of the Upper Roller Die by tightening the
Roller Tensioner Lever, add additional turns until the
bead is formed.
• Tighten the Roller Tensioner Lever Lock nut. (Fig. 10)
NOTE:
Do Not Over tighten as this may tear the metal
workpiece, jam the Roller Dies or deform the Frame.

• Crank the handle slowly as you move the metal
making sure that the marked guideline is followed.
• Keep the marked guideline aligned with the center of
the Upper Die. When you reach the end of the guide
line, you may re-roll the bead by turning the crank in
the opposite direction.
This produces a more sharply defined bead.
• When done, loosen the Upper Roller Tensioner lock nut
and retract the Upper Shaft and Upper Die.
• Pull the workpiece panel from between the dies and
check the finished result.
4.2 CREATING STRAIGHT BEADS
NOTE:
When forming beads, for greater ease in handling workpiece panels and achieving op-
timal accuracy, it is strongly advised to turn the handle slowly as you work. A variety of metals
and material gauge will produce a different result with the same dies and will require various
degrees of effort. Always perform a practice run with a piece of scrap material of the same type
and gauge before forming the actual workpiece.
